To all whom, it may concern.'

3e it known that I, JOSEPH STAUDER, manufacturer, a subject of theEmperor of Germany, residing at Engelufer 16, Berlin, in the Empire ofGermany, have invented new and useful Improvements in the Manufacture ofBrushes, (for which I have obtained Letters Patent from the followinggovernments, viz: that of Austria-I'Iungary, No. 2,295 and No. 3,806,dated April 24, 1393, France, No. 229,595, dated April 25, 1393; GreatBritain, No. 10,041, dated May 19, 1893; France, patent of addition toNo. 229,595, dated April 27, 1894; Italy, No. 36,675, dated June 27,1894, and Austria, No. 14e/3,614, dated July 11, 1394,) of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in the manufacture of brushes andbrooms of various kinds, its principal object being to provide means forgrouping the bristles,wires, fibrous material, or the like into bundlesor tufts in such manne-r that same may be readily inserted in orattached to the brush-head.

My invention further relates to means whereby the tufts of bristles maybe readily removed and replaced without interfering with the other tuftsin the brush.

Referring to the accompanying drawings, Figure lis an elevation, partlyin section, of a circular or disk brush. Fig. 2 is a horizontal sectionon line ze of Fig. 1. Fig. 3 isa similar section of a diskbrush providedwith a different arrangement of pins or pegs. Figs. t and 5 aresectional and plan views, respectively, of a sweeping brush or broom.Fig. 6 is a modified arrangement of the grooves for receiving thetuft-sockets. Fig. 7 is a modified construction of a disk brush; andFigs. 8 and 9 are sections of same on lines and fi/ y, respectively, ofFig. 7. Figs. 10 and l1 are side and front elevations, respectively, ofthe tufts for forming the `brush or broom in accordance withthisinvention.

The circular brush shown in Fig. 1 consists of two plates or disks a a',preferably secured by screws h, provided with washers b or the like forkeeping the disks at the desired dis tance apart.

On the inner surface and at the outer edge of the disk a are provided aseries of pins or pegs c, on which the metal sockets p, surrounding thetufts of bristles s, and being bent U shape, Figs. 10 and 1l, areplaced.. The disk a, provided with holes or recesses corresponding tosaid pins c, is now put on disk a', the two being then firmly screwedtogether by bolts or screws b, and the sockets p are thus secured andkept between the disks.

According to the modified construction shown in Fig. 3, both disks areprovided with pins or pegs d, being opposite each other when the disks aa' are screwed together, and thus securing the sockets p.

The head e of the brush or broom shown in Fig. et is provided withlongitudinal parallel grooves in which the U-like metal sockets p areplaced one after the other and then secured by a rail 71 passed throughor between said bent sockets, and nailed or screwed onto the brush-head.

In order to render the brush more eective for sweeping in alldirections, but especially parallel to the head of the brush, thegrooves may be made to cross the brush-head in zigzag form, as shown inFig. 6. By so arranging the grooves the open parallel spaces presentwith brushes having straight parallel grooves are avoided. In this casethe form of the rails h for securing the sockets ,p corresponds to thatof the grooves.

The circular brush shown in Fig. 7 is provided with a circular body E,in whose periphery are made recesses F, narrowing outwardly somewhat.

The bent sockets p of the tufts inserted into said recesses F from theside are nipped together by the narrower entrance to the recesses, andthus the pins,pegs, and rails shown in connection with the brushesillustrated in Figs. l and 4 are dispensed with. The sockets p, securingthe tufts s, are prevented. from lateral movement by the disks C C2,screwed onto or otherwise securedto the central body E of the brush.

Having now particularly described and ascertained the nature of thisinvention, I declare that what I claim, and wish to secure by LettersPatent, is-- 1. A brush or broom formed of a number of tufts of bristleseach contained within a U-shaped metal socket the said socket be- IOOing formed of a bent tube open at both ends, and surrounding andgrasping the tufts in their middle portions, in Combination With a bodyportion having chambers therein Within which the metal sockets aresecured, substantially as described.

2. A brush or broom, consisting,` of two oireular plates or disksprovided vnear their peripheries With pins or pegs forming recesses rowithin the outer edge of such plates, in oombination with tufts ofbristles contained in U -shaped metal sockets, surrounding the said pinsor pegs, substantially as described.

In Witness whereof I have hereunto signed my name in the presence of tWosubscribing 15
